Bile tolerance of L. plantarum was carried out for 240 min
exposure to simulated small intestinal juice (pH 8.0) with
0.45% bile salt (Huang and Adams, 2004; Michida et al.,
2006). As shown in Table 3 and Figure 4, in the control
experiments, all test strains were found to be capable to
survive during exposure to simulated small intestinal juice
with 0.45% bile salt for 240 min and the reduction of the
viable cells count ranged from 0.26 to 2.64 log CFU/ml.
Of thirteen strains, a slightly decreased viability was
observed in PKWD6-10 and PKWA6-1 and their cell
